365th Intelligence, Surveillance And Reconnaissance Group
The 1st Search Attack Group was a United States Army Air Forces unit that served during World War II. Its last assignment was with First Air Force. It was based at Langley Field, Virginia throughout its existence, and equipped with Boeing B-17 Flying Fortress, Douglas B-18 Bolo, and Consolidated B-24 Liberator aircraft. It was disbanded on 20 April 1944. The original mission of the group was the development of equipment and tactics best suited for aerial anti-submarine warfare. Among the devices that the group helped develop or test were the radar altimeter,The radar or absolute altimeter gives the altitude an aircraft is above the surface it is flying over, rather than the altitude above sea level given by the barometric altimeter. the magnetic anomaly detector, the sonobuoy, improved airborne depth charges, long-range navigation systems, and airborne microwave radar.Warnock, p. 23 The group also conducted training on equipment and antisubmarine tactics for Army Air Forces ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, Marine radar, ships, spacecraft, guided missiles, motor vehicles, Weather radar, weather formations, and terrain-following radar, terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio spectrum, radio or microwaves domain, a transmitting antenna (radio), antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a radio receiver, receiver and Data processing system, processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the ca ...

Magnetic Anomaly Detector
A magnetic anomaly detector (MAD) is an instrument used to detect minute variations in the Earth's magnetic field. The term refers specifically to magnetometers used by military forces to detect submarines (a mass of ferromagnetic material creates a detectable disturbance in the magnetic field); military MAD equipment is a descendant of geomagnetic survey or aeromagnetic survey instruments used to search for minerals by detecting their disturbance of the normal earth-field. History Geoexploration by measuring and studying variations in the Earth's magnetic field has been conducted by scientists since 1843. The first uses of magnetometers were for the location of ore deposits. Thalen's "The Examination of Iron Ore Deposits by Magnetic Measurements", published in 1879, was the first scientific treatise describing this practical use. Magnetic anomaly detectors employed to detect submarines during World War II harnessed the fluxgate magnetometer, an inexpensive and easy t ...

20th Bombardment Squadron
020 is the national dialling code for London in the United Kingdom. All subscriber numbers within the area code consist of eight digits and it has capacity for approaching 100 million telephone numbers. The code is used at 170 telephone exchanges in and around Greater London as part of the largest linked numbering scheme in the United Kingdom. In common with all other British area codes the initial '0' is a trunk prefix that is not required when dialling London from abroad. The 020 area code fully replaced older area codes for London on 22 April 2000, following multiple telephone number changes during the 1990s.020 could be used from 1 June 1999 and the previous 0171 and 0181 codes could no longer be used from 22 April 2000. As is the case for other codes in the UK, the 020 area code may also be used for services without any physical presence in the area, such as private networks or virtual numbering. As one such user is the Foreign and Commonwealth Office Telecommunication ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiation Laboratory
The Radiation Laboratory, commonly called the Rad Lab, was a microwave and radar research laboratory located at the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts. It was first created in October 1940 and operated until 31 December 1945 when its functions were dispersed to industry, other departments within MIT, and in 1951, the newly formed MIT Lincoln Laboratory. The use of microwaves for various radio and radar uses was highly desired before the war, but existing microwave devices like the klystron were far too low powered to be useful. Alfred Lee Loomis, a millionaire and physicist who headed his own private laboratory, organized the Microwave Committee to consider these devices and look for improvements. In early 1940, Winston Churchill organized what became the Tizard Mission to introduce U.S. researchers to several new technologies the UK had been developing. Among these was the cavity magnetron, a leap forward in the creation of microwaves that made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

En Cadre
A cadre (, , ) is the complement of commissioned officers and non-commissioned officers of a military unit responsible for training the rest of the unit. The cadre may be the permanent skeleton establishment of a unit, around which the full unit can be built if needed. In countries which have conscription, a cadre may comprise the permanent staff of a regiment who train the conscripts assigned to it. The term comes from the French expression ''en cadre'', with the same meaning. In the Military of the United States, a cadre is a group or member of a group of leaders, especially in units that conduct formal training schools. In United States Army jargon, the word is singular and plural. At the United States Military Academy, the upper-class cadets who conduct Cadet Basic Training for incoming freshmen are called the cadre. In the British Armed Forces, a cadre is a group of instructors or a unit that trains potential instructors or non-commissioned officers (NCOs), in which case it u ...

Squadron (aviation)
A squadron in air force, army aviation, or naval aviation is a unit comprising a number of military aircraft and their aircrews, usually of the same type, typically with 12 to 24 aircraft, sometimes divided into three or four flights, depending on aircraft type and air force. Land-based squadrons equipped with heavier type aircraft such as long-range bombers, cargo aircraft, or air refueling tankers have around 12 aircraft as a typical authorization, while most land-based fighter equipped units have an authorized number of 18 to 24 aircraft. In naval aviation, sea-based and land-based squadrons will typically have smaller numbers of aircraft, ranging from as low as four for early warning to as high as 12 for fighter/attack. In most armed forces, two or more squadrons will form a group or a wing. Some military forces (including the United States Air Force, United States Space Force, Royal Air Force, Royal Netherlands Air Force, Belgian Air Component, German Air Force, R ...
